LUBRICATING DEVICE.

Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed June 13, 1910. Serial No. 566,571.

To all whom it may concern:

Be it known that I, PLmN'r MGKINNEY, a citizen of the United States, residing at Argenta, county of Pulaski, and State of Arkansas, have invented certain new and useful Improvements in Lubricating Devices, of which the following is a specification.

My invention relates to lubricating devices and particularly to lubricatingl devices for the journals of the main drivers of a locomotive.

lVith the lubricators now in general use on locomotives considerable time and expense is required in repacking the same. The main pedestal brace must be removed and it requires a machinist and two helpers working for one hour to an hour and one-half to pack the journal box.

The object of my invention is to provide an improved lubricating device for journals whereby the journals of the main drivers of locomotives may be readily and quickly re packed, and whereby but one man is required -to do the work.

A further object of my invention is to provide a device of the class mentioned particularly adapted for the pur-pose stated but which may also be used in other places.

A further obj ect of my invention is to provide a device of the class mentioned which shall be of simple construction, efficient in operation and which will not readily get out of order.

Other objects will appear hereinafter.

lith these objects in view my invention consists generally in a journal box recessed at the bottom to receive a cellar, a hollow block or cellar therein having a perforated or foraminated upper wall curved to lit the journal, a spring pressed follower in the cellar having a filling opening therein and a closure for said opening, the bottom of the cellar also being provided with an opening in its bottom corresponding to the opening in said follower whereby access may be had to the cellar above the follower for filling the same with lubricant without the necessity of removing any of the parts of the journal box or adjacent portions of the machine.

My invention furtherA consists in certain means and construction whereby the follower plate may be retracted and held in retracted position while repacking the box.

My invention further consists in various details of construction and arrangements of parts all as will be fully described hereinafter and particularly pointed out in the claim.

My invention will be more readily understood by reference to the accompanying drawings forming a part of this specification and in which Figure 1 is a vertical longitudinal section through a ournal box equipped with a lubricating device embodying my invention in its preferred form, Fig. 2 is a transverse section taken on the line x--ac of Fig. 1, Fig. 3 is a. view similar to Fig. 1, illustrating the follower plate drawn down and the device opened for filling or repacking, Fig. l is a bottom plan view of the cellar, and Fig. 5 is a perspective view of the follower plate.

Referring now to the drawings 1 indicates the journal box, 2 the journal and 8 the hub of one of the main drivers of a locomotive. The box 1 is provided with the usual brass f1- and its lower portion is recessed as at 5 to receive the cellar G which is held in position by the usual bolts 7. The cellar comprises a hollow box-like member, rectangular in horizontal section and comprising a bottom 8, side walls 9 9 and end walls 10-10, the latter being curved at the upper edges to conform to the journal 2. The box 5 is open at the top and provided with a top plate 11 which is also shaped to fit snugly against the lower portion of the journal and is perforated or foraminated, 12 indicating the perforations. The bottom of the box or cellar is provided with perforated ears or lugs 13 to receive the bolts 7.

Arranged within the cellar is a horizontally disposed follower 14:. This comprises a rectangular plate coextensive in length and breadth with the inner dimensions of the cellar. The follower plate 14 is cut away at one end as at 15 forming an aperture or lling opening 1G through which the lubricant is inserted. The opening 16 extends but part of the way across the plate leaving the projecting sides or edges 17, the ends of which abut the end wall of the box 5 to maintain the plate in proper position and for a purpose hereinafter described.

Slidably mounted upon the upper face of the follower plate 1st is a thin plate 1S which forms a closure for the opening 16. By referring to Figs. 1 and 5 it will be noted that the portions 17 of the follower form supports or ways for the closure plate 18. The

plate 1S is provided with a depending flange 19 which extends downwardly between the portions 17 and constitutes a stop to limit the movement of the plate 1S when being' opened and also serves as means for opening` and closing' the same. An inverted conical spring 2O is interposed between the bottom 8 of the cellar and the follower plate let and constantly tends to force the latter upwardly together with the lubricant 2l resting thereon to maintain a constant supply of lubricant to the journal through the perforations l2.

The bottom 8 of the cellar 5 is provided with an opening 22, preferably somewhat larger in dimensions than the opening 16 in the plate lll, and directly beneath the same. By this construction it is evident that access may be had to the interior of the cellar and to the space above the follower plate for tilling the same without the necessity of removing any of the parts of the journal box or adjacent portions of the engine or machine.

Novel means are provided for retracting or depressing the follower let against the tension of the spring 2O to facilitate repacking the box. To this end the plate le. is provided with a pair of depending bolts or rods 23 having eyes Q4 at their lower ends.

Q5 indicates a weight of suflicient heft to draw the plate 14 downwardly against the tension of the spring 20. This is provided with a chain 0r chains 2G having` hooks 27 at its ends to engage the eyes 24. The weight and chain are only used when the box is being repaclred.

One of the bolts or rods 23 may extend through the opening 22 in the bottom of the cellar and said opening may be somewhat wardly as shown in Fig. 3.

sedere enlarged adjacent thereto as at Q8, whereas a smaller opening' Q9 is provided in the bot ton/1 of the box to give access to the eye of the other bolt or rod.

lVhen it is desired to repaclt the box the hooks 27 are inserted in the eyes 2li and the weight draws the follower plate le; downrllhe plate 1S is then moved bacl; as also shown in the same ligure to open the aperture 1G. rlChe grease or packing is then inserted above the plate ll and the plate 1S moved to close the aperture 1G. The weight 25 is then removed and the engine or machine is ready for further use.

Having described my invention what claim as new and desire to secure by Letters Patent is z- A journal box recessed at the bottom, a cellar arranged in the recess in said bex, a foramii'iated top for said cellar, a follower plate in said cellar cut away centrally at one end for a portion of its width forming a filling opening and a pair of projecting ends, a movable closure for said opening slidably mounted upon the upper face of said plate and said projecting ends, a spring .interposed between said plate and the bottom. of said cellar and the bottom of said cellar being provided with an enlarged unobstructed opening directly beneath said filling opening', substantially as described.

.ln testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.
